It wouldn't change anything for me.
It would still be Kes being destroyed, turned into an evil, crazy maniac with the intention to destroy the ship and kill the crew for no reason at all and then at the end becoming a pathetic wreck with the crazy, unrealistic intention to go back to a place were she didn't want to live.
Let's try huh? (I may not be able to change your mind but I'll give it a go) The good is she made it right and got home. I'd rather her feel at home with Janeway and co but it's better than just dead evil Kes.
